Hi,
I have been trying to figure out exactly how long my 120Vac input, 1440VA(865W), 120Vac output, UPS will last under load during a power outage.
It's APC's J Type Power Conditioner and Battery Backup J25B. Listing is https://www.amazon.com/APC-J25B-8-Outlet-Conditioner-Battery/dp/B003GSLL2E
Amazon give it's prediction but I wanted to calculate it out.
I know that I'm plugging to it a 120Vac load that draws at max 1amp.
so...VA = V X I
= 120V X 1A
= 120
How do I incorporate time? There has got to be another spec. variable I am missing?
Any help would be great.
Thanks
